Notes:
•
Cree Venture maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and
±2 on CRI measurements. See the Measurements section (page 22).
•
Cree Venture J Series 2835 18‑V LED order codes specify only a minimum flux bin and not a maximum. Cree Venture may ship
reels in flux bins higher than the minimum specified by the order code without advance notice. Shipments will always adhere to the
chromaticity restrictions specified by the order code.
◊ CRI R9 minimum is 0 for 80 CRI minimum LEDs and 50 for 90 CRI minimum LEDs, with a ±3 tolerance.
*
Flux values @ 85 °C are calculated and for reference only.
